BARL Bits 15–0 (break address 15–0 (BA15–BA0)): BA15–BA0 store the lower bit values
(bits 15–0) of the address of the break condition.
6.2.2
Break Address Mask Register (BAMR)
The two break address mask registers—break address mask register H (BAMRH) and break
address mask register L (BARML)—together form a single group. Both are 16-bit read/write
registers. BAMRH determines which of the bits in the break address set in BARH are masked.
BAMRL determines which of the bits in the break address set in BARL are masked. A reset
initializes BAMRH and BARML to H'0000. They are not initialized in the standby mode.
BAMRH: Break address mask register H.

BAMRH bits 15–0 (break address mask 31–16 (BAM31–BAM16)): BAM31–BAM16 specify
whether bits BA31–BA16 of the break address set in BARH are masked or not.
